Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, specifically to an aluminum particle drum screening device and screening process with multi-size separation function. Background Technology

[0002] Aluminum granules, also known as aluminum pellets or aluminum sand, have a bright appearance and are mostly cylindrical. They are widely used on the surface of aluminum, zinc, or thin-walled workpieces and can also be used in fireworks. Aluminum materials made into granules are easier to store and save a lot of floor space. While reducing oxidation, they also enhance the utilization of aluminum. Due to the advantages of high density, easy storage, and no greenhouse gas production during combustion, aluminum granules are expected to become a solution for replacing fossil fuels in the future.

[0003] However, after aluminum granules are produced, they are usually accompanied by a large amount of dust and debris. These substances will inevitably affect the normal production of aluminum granules. At best, they will cause a lot of scratches on the surface of the aluminum granules, increasing the rate of oxidation and corrosion. At worst, they will cause a large number of already formed aluminum granules to be crushed again, making the aluminum granules unusable. During the production process, aluminum granules of different sizes will also be produced. Since the storage methods and storage densities of each size of aluminum granules are different, they need to be classified and planned. This requires manual replacement of screens multiple times. Aluminum powder poses a significant threat to human health. Therefore, a device is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum particle drum screening device and screening process with multi-particle-size sorting function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an aluminum particle drum screening device and screening process with multi-particle-size sorting function.

[0006] The screening device includes a support frame, a support plate on the support frame, a stabilizing box on the support plate, a screening cylinder inside the stabilizing box, a stabilizing motor inside the stabilizing box, a swing box on the output end of the stabilizing motor, a swing arm on the swing box, and a end of the swing arm furthest from the swing box rotatably connected to the screening cylinder. A dust suppression box is mounted on the stabilizing box, and a high-pressure blower is mounted on the dust suppression box, with its output end connected to the dust suppression box. The stabilizing box contains a two-stage stratification chamber, a discharge port at the bottom of the stabilizing box, a discharge bucket inside the discharge port, and a discharge assembly inside the discharge bucket for screening. During the process, the mixed raw materials are first fed into the screening cylinder. Then, the stabilizing motor is started, and the stabilizing motor transmits power to the swing box. The swing box then transmits the power to the swing arm, which in turn transmits the power to the screening cylinder. Subsequently, the dust suppression box and the high-pressure fan work together to generate high pressure, which discharges debris and dust from the screening cylinder. The aluminum particles discharged from the screening cylinder are then sent into the discharge bucket. After feedback from the current change of the discharge component, the aluminum particles in the secondary stratification chamber are then sent into the discharge bucket. With the cooperation of the discharge component, multi-level information feedback can be performed to control the attitude of the stabilizing box.

[0007] A stabilizing track is installed on the support plate, and the stabilizing box is embedded in and slidably connected to the stabilizing track. A lifting hydraulic rod is installed on the support plate, and the output end of the lifting hydraulic rod is rotatably connected to the stabilizing box. The cylinder part of the lifting hydraulic rod is rotatably connected to the support plate. The lifting hydraulic rod is electrically connected to the discharge assembly through a wire. A sliding arm is installed on the stabilizing box, and the sliding arm is slidably connected to the support plate. During the screening and stratification process, the posture of the mixture will affect the screening speed and screening, as well as the degree of stratification. Therefore, adjusting the stratification state of the mixture is very important. By using the lifting hydraulic rod, the posture of the stabilizing box can be adjusted, and with the support of the sliding arm, the stabilizing box can slide more smoothly, while the stabilizing track will restrict the movement trajectory of the stabilizing box.

[0008] The screening cylinder includes a support cylinder and a conical cylinder. The support cylinder is rotatably connected to the stabilizing box, and the conical cylinder is rotatably connected to the support cylinder. The conical cylinder is provided with multiple filter holes and multiple layered tracks inside the conical cylinder. The support cylinder is rotatably connected to the stabilizing box, and multiple sliding plates and arc-shaped columns are provided in the layered tracks. The arc-shaped columns and sliding plates are in intermittent sliding contact. During screening, the conical cylinder will swing inside the support cylinder. While swinging, the arc-shaped columns in the layered tracks will slide in the layered tracks and drive the sliding plates to rotate, thereby striking the aluminum particles that are stuck together inside the conical cylinder. This can reduce layering errors and avoid clogging problems. Moreover, the setting of the sliding plates will not cause significant damage to the formed aluminum particles.

[0009] A swing gear is rotatably connected inside the swing box. The swing gear is connected to the output end of the stabilizing motor. A transmission gear is set inside the swing box, and the swing gear meshes with the transmission gear. A transmission rod is rotatably connected to the transmission gear. A swing groove is set at the end of the swing arm near the transmission rod. The transmission rod is embedded in the swing groove and slidably connected to the swing groove. The end of the swing groove away from the transmission rod is rotatably connected to the conical cylinder. The swing arm has a composite telescopic structure. While swinging and screening, the stabilizing motor will drive the swing gear to rotate. The swing gear will drive the transmission gear to rotate. After the transmission gear rotates, the transmission gear will drive the transmission rod to rotate. Using the transmission of the transmission rod, the transmission rod will drive the swing arm to swing, thereby driving the screening cylinder to rotate. The rotating screening cylinder will filter out aluminum particles, so that the layered aluminum particles can be discharged from the filter holes of different particle sizes on the screening cylinder.

[0010] The support cylinder has multiple filter holes, each corresponding to a filter hole on the conical cylinder. A filter handle is mounted on the stabilizing box and slidably connected to it. A locking key is also mounted on the stabilizing box and slidably connected to it. A selection cylinder is mounted on the stabilizing box and electrically connected to the discharge assembly via a wire. During screening, the selection cylinder rotates the support cylinder within the stabilizing box. When screening is required, the selection cylinder rotates the support cylinder, aligning the filter holes with the filter holes on the screening cylinder. Aluminum particles discharged from the screening cylinder pass through the support cylinder and enter the discharge cylinder, thus completing the initial discharge function. The orientation of the support cylinder is adjusted by the selection mechanism of the discharge assembly, thereby controlling the screening speed.

[0011] The discharge assembly includes a lifting plate and a lifting spring. The lifting plate is slidably connected to the discharge hopper. The two ends of the lifting spring abut against the discharge hopper. Multiple sliding switches are installed inside the discharge hopper. A trigger plate is installed at the bottom of the lifting plate. The movement trajectory of the trigger plate is on the same straight line as the installation position of the sliding switches. Each sliding switch is electrically connected to the selection cylinder and the lifting hydraulic rod through a wire. During the initial discharge process, the lifting plate will receive the discharged aluminum particles. Under the action of gravity, the lifting plate will slide inside the discharge hopper, driving the trigger plate to slide on the sliding switches, thereby triggering the sliding switches at different stages and sending different electrical signals. When the trigger frequency is too high, it indicates that the discharge speed is too fast or the weight of the discharged aluminum particles is too large. At this time, it is necessary to adjust the lifting hydraulic rod to raise the stabilizing box. The discharge speed will then decrease, and sufficient stratification will be achieved. After the discharge speed decreases, the height will be lowered again.

[0012] The secondary stratification chamber is equipped with multiple screening plates, each detachably connected to the chamber. The chamber has a discharge port, and each screening plate has screening holes. Multiple vibrating brushes are slidably connected to the swing arm, making contact with their respective screening plates. During screening, different screening plates will retain aluminum particles of different sizes. To ensure aluminum particles can pass through the screening holes, the swing arm drives the vibrating brushes to shake, causing them to vibrate at their contact points with the screening plates. This shaking of the screening plates allows the aluminum particles to move freely, achieving a shaking screening effect and thus separating aluminum particles of different sizes.

[0013] The dust suppression box is connected to the support cylinder. A flat-lay turbine is installed inside the dust suppression box, which is rotatably connected to the dust suppression box. A flat-lay mesh is installed inside the dust suppression box, and dust-suppressing strips are installed inside the stabilizing box, which are rotatably connected to the stabilizing box. The dust-suppressing strips are equipped with multiple spray nozzles and are connected to a water tank through a duct. During the screening process, in order to avoid damage to the surface of aluminum particles by dust and other substances, a high-pressure blower will drive the flat-lay turbine to rotate. The flat-lay turbine and the flat-lay mesh work together to homogenize the flowing gas, which then passes through the dust suppression box and the support cylinder, blowing the dust into the stabilizing box. Water mist can then be sprayed out from the dust-suppressing strips or the gas can be cooled in time to collect and remove the blown-out dust.

[0014] A screening process for aluminum particles with multi-size separation capability, the screening process includes:

[0015] S1. Pack the mixture into a box, vibrate it to separate it into layers, and then send it into a stabilizing box. After that, it enters a screening cylinder and waits for screening.

[0016] S2. Remove aluminum ash and hardened material and perform dust removal. The stable motor will drive the screening cylinder to operate for screening.

[0017] S3. Adjust the layer thickness and control the discharge speed. Adjust the angle of the stabilizing box by detecting the screening discharge speed.

[0018] S4. Vibration screening separates aluminum particles from different layers into batches, awaiting secondary screening;

[0019] S5. Aluminum particles of different sizes are discharged separately, and aluminum particles of different sizes are discharged from different filter layers respectively;

[0020] S6. Remove the aluminum ash that has been condensed and settled, and remove the impurities from the stabilization chamber.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The present invention adopts a structural component with dust reduction function, which uses the large amount of vibration generated during screening to remove a large amount of dust and aluminum powder generated during screening, preventing these substances from spreading into the air and avoiding health effects on operators. It also reduces the friction between aluminum powder and dust on aluminum particles and reduces scratch damage.

[0022] 2. This invention utilizes the detection of discharge speed to automatically adjust the posture of the screening device, thereby controlling the discharge speed. It can also detect the degree of discharge in each layer zone, while reducing the problem of excessive retention of aluminum particles. It can fully screen aluminum particles of different sizes, and also reduces the problem of aluminum particles blocking the filter holes, thus ensuring the screening speed.

[0023] 3. This invention uses a combination of multiple screening plates, which can fully screen out aluminum particles of different sizes. In the screening process, a circulating contact wheel brush contact structure is used, which can greatly reduce the occurrence of clogging problems and make the screening effect more accurate.

Therefore, adjusting the state of stratification of the mixture is very important. By using the lifting hydraulic rod, the posture of the stabilizing box can be adjusted.

The stabilizing motor 5 is started, which drives the swing gear 601 to rotate. The swing gear 601 drives the transmission gear 602 to rotate.

Water mist or timely cooling can then be sprayed from the dust suppression strip 803 to collect and remove the blown-out dust. The aluminum particles discharged from the screening cylinder 4 are then fed into the discharge bucket 11. During the initial discharge process, the lifting plate 1201 receives the discharged aluminum particles. Under gravity, the lifting plate 1201 slides within the discharge bucket 11, causing the trigger plate 1204 to slide on the sliding switch 1203, thereby triggering the sliding switch at different stages and emitting different electrical signals.
